Long‐wavelength stagnant lid convection with hemispheric variation in lithospheric thickness: Link between Martian crustal dichotomy and Tharsis?
[1] A dynamic link between the early evolution of Tharsis and the crustal dichotomy on Mars was recently proposed by Zhong (2009). We address in detail the fundamental aspects of the proposed model using 3‐D spherical shell modeling of convection. We investigate the conditions under which a spherical harmonic degree 1 flow is produced in the mantle of Mars in layered viscosity models with diffe...
متن کاملEstimates of Martian crustal thickness from viscous relaxation of topography
Isosta.tica,lly compensated crusta,1 thickness variations and associated topographic contrasts a,t the surface of a planet result in lateral pressure gradients, which may cause the lower crust to flow and reduce the relief. Areas of thicker crust are genera, lly associated with more rapid relaxation of topography. On Mars, topographic features such as impa, ct basins a, nd the hemispheric dicho...
متن کاملAn Analysis of the Variation of Ocean Floor Bathymetry and Heat Flow with Age
Two models, a simple cooling model and the plate model, have been advanced to account for the variation in depth and heat flow with increasing age of the ocean floor. The simple cooling model predicts a linear relation between depth and t •, and heat flow and l/t«, where t is the •ge of the ocean floor. We show that the same t • dependence is implicit in the solutions for the plate model for su...
متن کاملVariation of the axial location of Bruch's membrane opening with age, choroidal thickness, and race.
PURPOSE This study explores variation in the axial location of Bruch's membrane opening (BMO) to determine if this reference plane varies with age and race. METHODS There were 168 spectral-domain optical coherence tomography (SDOCT) optic nerve head volumes that were obtained from healthy subjects and manually delineated within 24 axial slices to develop point clouds for Bruch's membrane and ...
متن کاملVariation of nerve fibre layer thickness measurements with age and ethnicity by scanning laser polarimetry.
AIMS Scanning laser polarimetry is a new technique allowing quantitative analysis of the retinal nerve fibre layer in vivo. This technique was employed to investigate the variation of the retinal nerve fibre layer thickness in a group of normal subjects of different ages and ethnic groups. METHODS 150 normal volunteers of different ages and ethnic groups were recruited for this study. Three c...
